The surface winds that blow between the subtropical high and the equator are called trade winds.

Here's a breakdown:

* Subtropical high: These are areas of high pressure located around 30 degrees latitude in both hemispheres.

* Equator: This is the imaginary line that circles the Earth at 0 degrees latitude.

* Trade winds: These winds blow consistently from the subtropical high towards the equator. They are named "trade" because they were historically important for sailing ships engaged in trade.
